Sodium‐ion batteries are a promising substitute for lithium batteries due to the abundant resources and low cost of sodium. Herein, honeycomb‐shaped MoSe2/reduced graphene oxide (rGO) composite materials are synthesized from graphene oxide (GO) and MoSe2 through a one‐step solvothermal process. Experiments show that the 3D honeycomb structure provides excellent electrolyte penetration while alleviating...
Corneal neovascularization (CoNV) is a major cause of visual impairment worldwide. Currently, available treatment options have limited efficacy and are associated with adverse effects due to biological barriers and clearance mechanisms. To address this challenge, a novel topical delivery system is developed—Gel 2_1&Eylea—an aflibercept‐loaded eye‐drop hydrogel mediated with cell‐penetrating peptide...
The application of nitrogen‐doped porous carbon for sodium‐ion batteries (SIBs) has attracted tremendous attention. Herein, a series of edge‐nitrogen enriched porous carbon nanosheets (ENPCNs) are synthesized by annealing g‐C3N4 and glucose in a sealed graphite crucible at different temperatures (T = 700, 800, and 900 °C). Surprisingly, under the closed thermal treatment condition, the ENPCNs‐T possess...
Thin film catalysts, giving a different morphology, provide a significant advantage over catalyst particles for the gas evolution reaction. Taking the advantages of sputter deposition, a high entropy alloy (HEA) thin film electrocatalyst is hereby reported for the oxygen evolution reaction (OER). The catalyst characteristics are investigated not only in its as‐deposited state, but also during and...
Cell mechanical forces play fundamental roles in regulating cellular responses to environmental stimulations. The shortcomings of conventional methods, including force resolution and cellular throughput, make them less accessible to mechanical heterogeneity at the single‐cell level. Here, a DNA tensioner platform is introduced with high throughput (>10 000 cells per chip) and pN‐level resolution...
Vacancy engineering is an effective strategy to enhance solar‐driven photocatalytic performance of semiconductors. It is highly desirable to improve the photocatalytic performance of composite nanomaterials by the introduction of vacancies, but the role of vacancies and the heterostructure in the photocatalytic process is elusive to the composite nanomaterials. Herein, the introduction of I vacancies...
Black phosphorus nanobelts are fabricated with a one‐step solid–liquid–solid reaction method under ambient pressure, where red phosphorus is used as the precursor instead of white phosphorus. The thickness of the as‐fabricated nanobelts ranges from micrometers to tens of nanometers as studied by scanning electron microscopy. Energy dispersive X‐ray spectroscopy and X‐ray diffraction indicate that...
